I calculate that 441 ci = 7.2267 litres. 7.2267 litres / 8 = 0.9033375 litres per cyl.

Why do it? Because it gets used (not on all model/years, but most pre E40 ones) to calculate airmass. If you've tuned your entire VE with a wrong value (I'm guessing the default 0.708), then you need to multiply your entire VE by the ratio of old volume vs new volume. So if the new is 0.9033 and the old is 0.708, the ratio is 0.784. So take your (ridiculously high) VE table and multiply it by 0.784 and now you're closer to reality. That's it.
That was one of the issue with a car i have been working on just found it, found a recipte where it has a different crank, rods and pistons larger than 6.2L that should make thing come more inline with normal.
